The fire that blazed for more than three hours Sunday at Gerbers of Montanas machine and fabrication building is considered under control, according to Chief Steve Hester of Great Falls Fire/Rescue. “I think the fire is pretty much out,” Hester said. “Were trying to keep an eye on it, though, because some of that stuff is pretty insidious.” As of 5 p.m. Monday, the remaining fire crew hadnt put any water on the building for the last 5 to 6 hours, but Hester said all it takes is a hot ember inside a wall to start things up again. A crew was stationed at the building all day Monday and planned to stay there until at least late Monday evening, when GFFR would reassess the situation.
